One of the field in my custom object (Program__c) is a contact lookup field (Client__c).  How do I insert a new custom object with an existing contact without getting the this exception:

com.sforce.ws.SoapFaultException: A duplicate value was specified for field 'Id' in object 'Contact'

Thanks,
 

SObject[] records = new SObject[1];

	try {
		StringBuilder sb = new StringBuilder();
		sb.append("SELECT Id, FirstName, LastName, AccountId, Account.Name ");
		sb.append("FROM Contact ");
		sb.append("WHERE AccountId != NULL ");
		sb.append("  AND Id = '003d000002w3njaAAA' ");
		QueryResult queryResults = connection.query(sb.toString());
		SObject contact = null;
		if (queryResults.getSize() > 0) {
			contact = (SObject)queryResults.getRecords()[0];
		}

		SObject so = new SObject();
		so.setType("Program__c");
		so.setField("RecordTypeId", "012d0000000hQlHAAU");
		so.setField("Client__r", contact);
		so.setField("Marital_Status__c", "Separated");
		so.setField("Level_of_Care__c", "Inpatient");
		so.setField("Caller_Caregiver_Name__c", "Caregiver Name");
		so.setField("Patient_Type__c", "Impatient Discharge");
		so.setField("Admission_Date__c", new Date());
		so.setField("Projected_Discharge_Date__c", new Date());
		so.setField("Facility__c", "Grossmont");
		so.setField("Notes__c", "Test record added by Minh...");
		records[0] = so;

		// create the records in Salesforce.com
		SaveResult[] saveResults = connection.create(records);

		// check the returned results for any errors
		for (int i = 0; i < saveResults.length; i++) {
			if (saveResults[i].isSuccess()) {
				System.out.println(i+". Successfully created record - Id: " + saveResults[i].getId());
			}
			else {
				Error[] errors = saveResults[i].getErrors();
				for (int j = 0; j < errors.length; j++) {
					System.out.println("Error creating record: " + errors[j].getMessage());
				}
			}
		}
	}
	catch (Exception e) {
		e.printStackTrace();
	}
